What is the trigger since last home value while cranking. Should be 30 at all times with the Renesis wheel. If it's not 30, you have a trigger issue. Contact me if that's the case.

How are you checking for spark? Timing light or actually inserting a plug in a wire, grounding it, and visually confirming spark? Timing lights are finicky and may or may not strobe consistently. Visually verify spark with a plug.

Are the plugs in the engine fouled? If they are, you may not get a light strobe and it certainly won't start.

I told Jacob to space the sensor at .040". That should be good but confirm that with FFE. Their kits are pretty darn consistent and you shouldn't need to shim it.

This I'm unsure of, I didn't set the Haltech up. Jacob may know.

Both, with a new plug grounded and with a timing light.

The plugs are definitely bad, I ordered replacements which will arrive sometime today.

We did adjust it and got it around .035/.040 I also sent FFE an email requesting where I can purchase a replacement sensor locally as there's no time to order one.

Being in a hurry is your biggest enemy right now. That rarely produces good results.

You need to check the trigger since last home value before moving on. Do you even get an RPM value in ECU Manager while cranking? The VR sensors never go bad. I highly doubt a failed sensor is your issue.

Email me the map your working with. If you have WiFi available where the car is, download the Team Viewer software from teamviewer.com and let me know a good time and I can remote in and try to help you troubleshoot.

I'm not in a rush anymore, I'm content with driving the daily now. That and I really don't know what else to do.

I'll admit that I'm stupid with this stuff, I'll get help to do this after DGRR

i was not watching triggers since last home, but just verifying that the trigger counter increasing while cranking. there was an RPM value in ECU manager while cranking, but it was inconsistent.

what's strange is that we had this set up correctly on sunday: rx8 style trigger settings (vr sensor shimmed to .030), direct fire ignition typical settings, zero'd the timing, got it running nicely, and planned to do a street tune the next evening.
then the next day, poof, no spark except once when turning the key to ON and once or twice while cranking (seemingly randomly). this happened with both the timing light and an additional NEW spark plug attached to one of the coils while cranking.
last night we re-shimmed the trigger from .030 to .020 and then to .040 just for troubleshooting, and it seemed to make no difference. i also changed the trigger voltage up and down slightly and their original settings (which were being used sunday) seem to work best.

things we did not do last night:
1. replace all 4 spark plugs with new spark plugs
2. watch triggers since last home

if the spark plugs don't fix it i'm stumped. the teamviewer idea is probably best at this point, ludwig, if you can do that at some point this evening.

After taking a short break from the Mazda to calm down from a temper tantrum I threw last week that ended with a hundred piece timing light puzzle, I got back on it Saturday. If I recall the rage stemmed from the car still not starting after replacing the trigger wheel sensor. .

With new timing light purchased and in hand, my cousin stopped by and helped me out early Saturday, he held the unmounted sensor close to the wheel and moved it while I cranked the engine. We got it running so I added spacers based off the gap he recalled seeing between the sensor/mount. From there we took it for a test drive around town without any issue, even hot start was good. Later I met up with Jacob to start with street tuning, we put some miles on it and got it pretty close. We are at a stopping point till I complete my intake/filter assy.

Here's the big kick in the nuts! That evening during intermission of the playoff game with other rotard friends over that were equally excited to hear my car was finally running, I attempted to start it for them. . . No start!

Issues were with the trigger specifically. We would get plenty of trigger hits, but never home hits, and therefor the trigger since last home would also be wacky. Also we'd get the occasional "miss" which relates to those missed homes. Has anyone else had the below issue? Is this indicative of a interference or wiring (connection) issue? The car does run and drive great when the issue is not presenting itself, and it doesn't really come and go, just either does work, or doesn't. Almost at the "wiggling wires" phase.

It is an FC engine with FFE reluctor trigger. Hall effect isn't an option with sprintRE IIRC, but the most people have great luck with the SprintRE and the FFE triggers. (usually plug and play).
